Comment Jesse should put his money where his mouth is. (Score 1) 397

Companies only see green. They don't care about any other color, unless it equates to more green.

Rather than force the companies to hire people who they don't think are qualified, why not sponsor some minorities for 7+ years to them interested in CS and get them a good degree in CS.

Or better yet, Jesse should shut his mouth, go get a technical degree himself, and then do some real work. IMO, he talks a good game, but he doesn't back it up with his lavish lifestyle.

Comment We are talking about four bright pixels here... (Score 4, Interesting) 73

Just to be clear for those who didn't read the article, this entire study is based on four brighter than expected pixels.

Four pixels in the images are brighter than one might expect from reflecting sunlight, Barnes reported at the conference. He concluded that they must represent something particularly rough on the surface — a wave or set of waves.

I see her as a mass murderer. People have died as a direct result of her bullshit. She ought to be put through the justice system in the same way that someone impersonating a doctor would be tried for a death resulting from his or her false medical advice. Except in her case, it's not just one death, it's a whole lot of deaths. Sure, it's not solely her fault, but it doesn't have to be (nor should it need to be) in our justice system.

Really?

She is a bleach blonde playboy model that only graduated high school. Other than being a recipient of botox and breast implants, she has no medical training or experience.

Why are people taking medical advice from her over their doctors?

The only way to get through to the anti-vaxxers will be to give them a choice: get the shot or be quarantined with the other anti-vaxxers in a remote region of the country with no travel allowed. Nature will take its course.

Comment Re:Go find another thread to whine in (Score 2) 309

There a topic that isn't about America? Well can't have that! Spin it to be about America! Redirect all topics to be on America, particularly whining about America!

What's ironic is that the folks who tend to do this, are just as likely to sneer that Americans don't care about anything happening outside the US.

Well, Americans don't really care about anything happening outside the US, unless it affects them. Even the US government is that way... why are they not in Ukraine right now while this democratic country is under attack by "unspecified" militants? The US was happy to roll into Afghanistan (for revenge) and Iraq (for oil) at a moments notice. No problems helping dispose of their old enemy Gaddafi either. (Libya has oil, right?)

The Europeans can't complain much though as they are even softer on military intervention! They were excited about the Ukraine's merging with the EU, but all it took was a little posturing from Putin to reduce the European states to hand-wringing and empty threats. Why? Because they are whores for Russia's oil and have no backup plan in place were Gazprom to cut them off.

Finally, Asia and South America only care about their own continents. So pretty much everyone only cares about themselves.

I am surprised that no one is calling Putin's bluff however. He's refused to acknowledge that the "pro-Russian" troops are Russian. It seems like a good way to force his hand would be to start rolling heavy military equipment into the rest of the Ukraine to protect it from the "terrorists" in Crimea. Then, when Russia starts saber-rattling, NATO should start testing their ballistic missile and interceptor assets... You know, to protect the Russians from the Crimean terrorists. Bullies only respect other bullies.

Comment Yeah, OK... (Score 1) 712

Too bad they don't also have a concrete plan to match the decrease in coal-generated power with something more environmentally friendly.

From the article:

If at the same time the US accelerates expansion of renewable energy sources and transmission facilities, this could be accomplished with no interruption to electricity supplies, adding only about a penny or two to each kilowatt-hour on electricity bills.

It's be more useful to spend 50 billion developing and installing cost-effective renewable energy sources that are cheaper than coal. Then coal would go away on its own via capitalistic drivers.

Comment Stop being cheap or collecting so much crap data! (Score 2) 983

What does it mean that he didn't have "a good way to backup that much data, so he never took one"?

The concepts behind backing up data have not changed. You need to manage the size of your data to redundantly fit into the storage of your system. So either pony up the cash and time to properly store your files, stop collecting TBs of crap, or stop complaining about losing it when your system crashes.

It's frustrating to see people continuously complaining about how they have too much data to back up cheaply and conveniently. It's even more frustrating to see them complaining about losing all of their data because they didn't back it up properly.

I think that the main issue is that most people do not realistically or conservatively plan their actual storage capability. For example, it seems like 90% computer users believe that having 4 TB of hard drive space means that they can safely store 4 TB of data.

After a conversation about scratch space, redundant drives, and timestamped backups, they then will grudgingly agree to allocate 25% of their available storage to RAID/Backup space, which obviously does not get the job done! Very few are willing to accept using 66% of their available hard drive space for RAID and Backups, which is really the minimum metric for any sort of storage longevity.

20 TB is an awkward amount of data for a non-corporate individual to be storing. It's more data than most people actually need for their media and it is getting into a very expensive price range to backup for basic music/movie content. (By expensive, I mean that it would be cheaper to just re-purchase the media rather than back it up.)

Comment Re:Lat / Long? (Score 1) 461

I can see how a constant stream of telemetry might be cost-prohibitive, but what about a squirt of data consisting of -

- Flight Number

- Lat / Long

- Airspeed

- Groundspeed

- Altitude

- Compass heeding ...sent every five minutes? At least that would give a 'last known' location.

They already have something like this. It's called a transponder. But when it stops transmitting or is turned off, you are back to the current problem.

Comment Women apparently suck at math and men can't read. (Score 1) 384

Before you mod me down, read my post (and the article)!

What really surprised me was that the article text actually states that women's math scores were below that of men in every country tested:

Although the female test-takers lagged behind males on the math portion of the test, the size of the gap closely tracked the degree of gender inequality in their countries, shrinking to nearly zero in emancipated countries like Sweden and Norway. That suggests that cultural biases rather than biology may be the better explanation for the math gender gap.

So apparently, it is entirely objective to state that the test results indicate that women are worse at basic math than men. Except in Iceland.

Woman apparently are also always better at reading comprehension than men. (See the article.)

The authors argue this results from misogynistic prejudice. However, if you look at the actual article, the correlation is not exact. Norway and Sweden are more emancipated than Iceland, yet have lower female math scores relative to the males. Portugal, France and Poland also introduce a deviation from the trend. Thus, 5 of the 10 countries evaluated do not correlate well with the authors' suggested trend, indicating that the emancipation index is probably not the right metric to be comparing to.

Comment Re:In my experience (Score 1) 384

Actually, you do learn math by rote memorization. Those of us who were interested in math from the beginning were training it all the time by playing around with numbers or geometrical objects, which is just rote memorization with spices on top. And you get really good at math by doing math chores all the time.

That's not really true at all. Rote memorization just teaches you the sets of numbers that you have memorized. Actual understanding of the addition process allows one to add any set of numbers, even if they have never seen them before. In fact, with proper teaching, you should be able to add properly, at first attempt, with no memorization required.

Teaching the method rather than memorization is much more efficient given that there are, by definition, an infinite set of numbers.

Sadly, the US teaching methodology forces everyone to memorize basic concepts first. Most teachers then muddle through the theory so poorly that only students with good aptitude and home lives are able to extract the general methodology in a decent amount of time. The rest fall back on memorization for a few years until they forget entirely. Then they spend the rest of their lives terrified of math.

Comment Let's look at some numbers (Score 1) 545

Gallons-to-tons as the metric? What happened to meters and kilograms?

Let's look at the energy content for some different meat and vegetable products:
Lean steak: 1.86 cal/g
Lard: 8.85 cal/g
Broccoli: 0.34 cal/g
Beets: 0.31 cal/g
Meat products appear to contain between 5 and 29 times more energy per unit gram than the vegetables while requiring 47-77 times more water using the author's unchecked (but I assume biased!) stated water usage values).

So the ratio of energy/water usage ratio for meat versus vegetables is about 3.5:1. That isn't as egregious as the OP makes it sound.

Also, many meateaters will not replace their meat diets with legumes, nuts and tubers. Just like many vegetarians will not replace their legumes, nuts and tubers diets with meat.

If you have any experimental data to show, you are going to need some sort of viewgraph projector or computer display. I don't think that many of ones colleagues would be content to trust that your hand-drawn data points agree perfectly with your hand-drawn "theory" curve!

That said, it is fantastic to see people going back to the chalkboard. What is really unfortunate is that most places have ripped out their chalkboards, replaced them with dry erase boards, and then stopped stocking them with fresh markers.
